This series incorporates front and side LED screens. They were designed to replace existing ones, so they are fully compatible with them. They use the same communications protocol, which was investigated 'in situ', and have the same size and mechanical fixations as the original ones.
These LED screens are characterized by their high luminosity, their robustness and their high readability. The front LED screens have a high resolution, allowing a great readability in the distance; and the side teleindicators use a clear lettering, for better visibility over shorter distances.
